It's believed the humble
watermelon boasts properties that can boost blood flow to the penis. Erectile
dysfunction, also known as impotence, is the inability to get and maintain and
erection.
It can
have a range of causes, including narrowing of the blood vessels, a problem
usually associated with diabetes, high cholesterol and high blood pressure.
While
some men opt for Viagra as a way to treat the condition, experts say watermelon
can be used as a natural treatment thanks to the amino acid citrulline, which
can help ‘relax’ blood vessels.
Lily
Soutter, Nutritionist at lilysoutternutrition.com said: “Watermelons have now
been coined as nature’s Viagra.
“Research
has shown that these effects are down to their high concentrations of an amino
acid called citrulline.
“When consumed, citrulline is
converted into the amino acid arginine, which boosts nitric oxide – the
responsible agent for relaxing and dilating blood vessels.
“This
effect can improve blood flow to the penis, which is just how Viagra works to
treat or prevent erectile dysfunction.”
A
scientific study in 2011 concluded that citrulline consumption had a
‘significant positive impact’ for people suffering with mild erectile
dysfunction.
Researchers
gave men with mild erectile dysfunction a placebo for one month and a
citrulline supplement for another month recording the hardness of their
erection and the amount of times they had sex.
Scientists
tested a total of 24 patients, with an average age of 56. The results showed:
“The improvement in the erection hardness score from three - mild erectile
dysfunction to four - normal erectile function - occurred in 2 (8.3 per cent)
of the 24 men when taking placebo and 12 (50 per cent) of the 24 men when
taking L-citrulline.”
Experts said the L-citrulline
supplements were proved to be ‘safe’ and ‘well accepted’ by patients.
Eating dark red watermelons can also boost levels of lycopene, a plant
antioxidant which gives the fruit its red colour.
Lily
said: “Interestingly we now know that red watermelons contain even more
lycopene than tomatoes.
“Lycopene
has also been shown to help relax blood vessels and increase blood flow to the
penis, just like viagra.
“It is
important to note however, that as lycopene is a fat-soluble antioxidant, it is
absorbed best when combined with fat.”
Experts
also advise that eating watermelon with healthy fats such as avocado, seeds or
yoghurt can increase the absorption rate of lycopene by as much as five to
seven times.
Side effects of Viagra include
warmth or redness in the face, neck or chest, headaches, nausea, diarrhoea, and
sometimes even a loss of hearing and dizziness.
However,
unlike Viagra, watermelon consumption comes with no side effects if it is eaten
in moderation.
Lily
said: “Watermelon is a great alternative for those who are not medically fit to
take erectile dysfunction medications.”
NHS
Choices said: “Erectile dysfunction is a very common condition,
particularly in older men. It is estimated that half of all men between the
ages of 40 and 70 will have it to some degree.”
